Mapping Maine cancers. An article by Dr. Janet M. Hock, Dr. Chris Farah, and Dr. James H. Page in Directions Magazine

Maine's predominantly rural population of 1.3 million has the distinction of having the oldest median age in the United States, as well as the more dubious distinction of having one of the highest age-adjusted incidence rates for all cancers in the country. Indeed, since 2000, Maine has consistently ranked among the top three states in cancer incidence for all anatomical sites and for persons of all ages, races and genders (National Program of Cancer Registries, 2009 #92). Figure 1 shows the incidence rates for 15 common cancers mapped against Maine's 16 counties, showing that Maine's age-adjusted cancer incidence rates are significantly different from the confidence intervals in the U.S. overall.

Research explores link between cancer and the environment. A report by Keith McKeen for MPBN Radio, Bangor, Maine

At least that's the goal of research now under way at the recently-established Maine Institute for Human Genetics and Health, headquartered in the city of Brewer. The Institute's director claims that rural Maine is an ideal location to explore the relationship between cancer genes and risk factors in the environment. To listen

Navigating forestland transactions. An article by Vice President Bret Vicary, PHD, MAI, in The Consultant

The mass sale of forestlands across the United States by the forest industry has provided the resources to fuel surging interest in forestland as a financial asset. Nowadays, most of the investment-grade forest assets changing hands across the nation are being scarfed up by Timber Investment Management Organizations (TIMOs) and Real Estate Investment Trusts (REITs). The TIMOs represent mainly institutional investors such as public and private pension funds, endowments, foundations and high-net-worth investors. Hedge funds and other private equity investors are getting into the game too. In certain regions of the country, privately held forest industry is acquiring timberlands too. Finally, non-profit investors such as The Nature Conservancy, local land trusts, and public agencies are increasingly part of the investor pool. Read more
